NAT’S ALL, FOLKS

The real-estate force is apparently with Natalie Portman, who’s found a buyer for her West Village condo in this descending market.

The “Star Wars” minx has just gone to contract to sell her apartment in Richard Meier’s transparent tower at 165 Charles St. The condo last had an asking price of $6.55 million.

Included in the convertible three-bedroom, three-bath, fifth-floor apartment are views in three directions, a 32-foot balcony and a spacious great room. Building amenities include a 24-hour concierge, a fitness center, an infinity-edge lap pool and a screening room.

Portman, who recently ended her relationship with folk singer Devendra Banhart, bought the glassy 2,500-square-foot, river-fronting unit in 2005 for $5.7 million. She first listed the unit in June for $6.7 million. A month later, she lowered the figure to its current price.

Andy Fink and Nancy Teague of the Corcoran Group are the listing brokers.

Buy all Mean’s

The price of Mean Manor just got $30 million leaner.

Leona Helmsley’s 40-acre estate in Greenwich, Conn. – known as Dunnellen Hall – has been slashed from $125 million to a more svelte $95 million. The massive, 14-bedroom Jacobean residence, which went on the market in February, includes a winter garden with a 52-foot indoor pool, palatial public rooms, a theater, a wine cellar and tasting room, a gym, a music room, servants’ quarters and views of the Long Island Sound. The gated grounds feature a 72-foot outdoor pool with a cabana, a tennis court, two guest cottages and a koi pond with a waterfall.

It also comes with a dubious history of former owners whose lives were ruined while living under its expansive Ludowici roof. The last of whom was Leona, who died there last year and who spent time in the slammer for writing off improvements to the spread as business expenses.

It’s also where she infamously uttered, “Only the little people pay taxes” to a servant.

Christie’s Great Estates still represents the property.

While residential-listing prices all over Greenwich and Westchester are dropping faster than Larry Craig’s pants in an airport bathroom, we’ve never seen a price cut of this magnitude. It makes Mel Gibson’s recent $4.5 million reduction on his now $35 million Greenwich property look a tad chintzy.

The discounted Helmsley property now ties a 263-acre estate in nearby North Stamford that straddles the Connecticut/New York border as the priciest suburban property.

Plaza dis-Astor

Could the situation at the Plaza be getting so embarrassing that owners are taking their overpriced apartments off the market? German businessman Juergen Friedrich’s $55 million “Astor Suite” listing was yanked after only one day.

E-mail messages to his broker went unanswered.

Meanwhile, at least six units have disappeared without a buyer in the past two months, ranging from a $1.95 million studio to a two-bedroom place that was reduced to $11.7 million before vanishing seven weeks ago.

That leaves 26 apartments with “for sale” signs, according to StreetEasy. One two-bedroom apartment, unit 1313, went on the market in April at $9.95 million and was just reduced by a million bucks.

After some negative Plaza reports surfaced, Corcoran Group broker Carrie Chiang called us to ask if we wouldn’t mind saying that the Plaza apartments are “much better from the 12th floor and below” before she listed a $46 million place on the fourth floor.

“They have higher ceilings and bigger windows,” she said.

But the stench of equine effluence from waiting carriages on Central Park South is even more nauseating when lower-floor residents open those larger windows.

Au revoir, Pierre

Just last week, we commemorated the fourth year of the $70 million Pierre triplex penthouse listing – and now it’s vanished from the Brown Harris Stevens Web site.

While brokers Elizabeth Sample and Brenda Powers couldn’t be reached, sources at the firm confirmed that owner Martin Zweig has taken the place off the market.

When the 16-room residence’s listing first appeared in October 2004, it was not only the most expensive apartment in New York, it was also the second-priciest property in the country – lagging only behind Three Ponds Farm in the Hamptons.

At last check, it had the third highest asking price in Manhattan. No. 1 is an $80 million condo at 15 Central Park West.

Located on the 41st to 43rd floors of the famed Fifth Avenue hotel, the Chateau-style abode features a 2,800-square-foot living room that once served as the Pierre’s ballroom. It includes five bedrooms, seven bathrooms and four terraces.

And included at no extra charge for the nearly $39,000 monthly maintenance charge is twice-daily maid service and mints on the pillows. Good night.
